You can't park at the Fire Station, but you can stop around the corner on Adirondack. Also an easy walk from the monthly Canada's Capital Cachers "meet and eat" event location at Summerhays Grill, or from College Square Plaza.
Update May 3, 2017: Given the history at this location, I have changed the cache to a micro. The cache is now a camouflaged finger-sized bison tube. Please BYOP. No room for trades or TBs.
